开发了一套水包油滴（O/W）乳化液冷轧薄板入口油膜厚度计算系统。利用该估算系统计算了薄板轧制和钢卷轧制时的入口油膜厚度。卷轧时入口油膜厚度大于板轧时。为了估算O/W型乳化液冷卷轧制过程中轧辊-轧件界面入口处的油膜厚度，提出了一种基于饥饿模型的数值计算方法。该模型由常规饥饿模型和平板模型的组合组成。采用新的饥饿模型数值计算方法，改变摩擦学因素，计算了进口油膜厚度。利用所提出的数值计算方法，可以合理地估算由该估算系统实验得到的进口油膜厚度。
A calculation system of the inlet oil film thickness in cold sheet rolling with oil droplets-in-water (O/W) emulsion was developed. The inlet oil film thicknesses in the case of sheet rolling and coil rolling were calculated using the estimation system. The inlet oil film thickness in the coil rolling was larger than in the sheet rolling. In order to estimate the inlet oil film thickness at the entrance to the interface between roll and workpiece in cold coil rolling with O/W emulsion, a numerical method was proposed using the starvation model. This model consisted of a combination of the conventional starvation model and the plate out model. The inlet oil film thicknesses were calculated, changing the tribological factors, using the numerical method of the new starvation model. By using the proposed numerical method, the inlet oil film thickness obtained experimentally using the estimation system could be reasonably estimated.
